type 2 cross recessed (phillips type) drive dimensions
(OP)
We're working on a #4-40 fastener (similar to a flat head (82 degree) that is to have a type II cross recessed drive on the head. I'm looking for detailed dimensions on the actual female drive for the screw as it will be a custom molded part. I've not found complete information anywhere and the info that I have found contradicts itself when to take "specifications" from one source and marry them to another. The ANSI 18.6.3 gives a start but does not give angles on the sides of the drive nor the details of the bottom.
Any help would be appreciated as I can back into this via testing and measurements but would rather find a spec if its available.

B18.6.7M gives the info for metric screws, not sure if it has the missing info you can read across.
